I have for sale a TST Comp box it has the latest flash as of beging of April. I just don't use the box enough to have it. It has the pyrometer and in cab controller with 0-9 settings on the torque and horsepower. I have the orginal instructions with it. I don't think I have the original box though. I guess it looks like there going for around $550 in here. my email is [email protected] or pm on here with any questions.
